title: 2-Chloro-6-(2,3-di-chloro-benzene-sulfonamido)-benzoic acid.
abstract: In the title compound, C13H8Cl3NO4S, the aromatic rings are oriented at a dihedral angle of 68.94 (1)° and the mol-ecule adopts a V-shape. An intra-molecular N-H⋯O inter-action generates a six-membered S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds involving the carb-oxy group link the mol-ecules into inversion dimers with an R 2 (2)(8) motif. N-H⋯O and non-classical C-H⋯O inter-actions connect the mol-ecules, forming sheets propagating in (100).
